Engine overheating is one of the most common causes of a vehicle stalling or breaking down. There are several potential reasons why it happens, and when you understand the causes, you’ll have a better idea of how to prevent problems and the need for engine repairs in the future. Here’s what you should know about why engines usually overheat and what you should do about it. 

What Causes an Overheated Engine?

Coolant is responsible for keeping your engine at a safe running temperature. When there are leaks in the radiator’s coolant reservoir, the engine is much more likely to overheat. It’s also possible that you’re using the wrong coolant or the ratio of coolant to water is incorrect. Additional causes of engine overheating include blocked coolant hoses, radiator fan failure, and a broken water pump. 

What Should You Do When It Happens?

If your vehicle’s engine overheats, you should immediately look for a safe place to pull over. Allow the engine to completely cool before taking a look under the hood. Check the radiator’s coolant level, and if it’s low, add more to the reservoir. Restart your vehicle, and make sure the temperature gauge remains steady before driving. If it overheats again, take your car to a mechanic for engine repairs. 

How Can You Prevent It?

Keep a spare gallon of coolant, along with a gallon of distilled water, in the trunk of your vehicle, especially when you go on long road trips. As soon as you notice the temperature gauge rising on the car’s dashboard, you can pull over and add water and coolant to your radiator before overheating occurs. Additionally, take your vehicle to an engine repair shop once per year, and allow the mechanics to check the hoses, fan, and water pump for proper function.
